Trying to select a propeller?

I'm looking for a good prop to fit my Rans S6S w. Jabiru 3300 engine. So far
two have failed to satisfy:
1. Wooden Jabiru J400 propeller, too easy to overrev the engine
2. 3-blade composite Warp drive, not enough cooling due to lack of airflow
near the hub

Candidates so far a
1. Tennessee wooden prop, heard some good things about it but have not seen
one in 'real life'
2. Wooden GT prop, looks great, seems to be good quality, said to perform
well
3. Sensenich composite ground adjustable, versatile, good reputation vendor,
but my co-builder thinks it's ugly...

Any advice from the group is appreciated.
